[LargeFormat] multi coating

[Les Newcomer]

This is the confusing part.

I hear/read:

You can only do single elements, or recement multiples because  the
process ruins the cement.

The price is too high, you can't do any thing.


So Clive shows up with a TR that has FIVE elements in a cell and it's coated.

So somebody dissassembled and then recemented and recolated two five
element cells just to get a single coating?
